json组装

组装json:
1,建立对应结构的实体：
一层括号一个类（多个实体分开来建立，否则识别不到）
json到实体没有重复的属性数不需要executive的，list的格式会转化类变成MorphDynaBean。
======
你需要在JSONObject.toBean的时候把list的元素类型当成参数传进去。代码如下，你肯定看得懂MapClass> classMap = new HashMapClass>();classMap.put("list", B.class);A j = (A) JSONObject.toBean(json, A.class,classMap);

======
实体到json有建立的jpa相互关联的要排除，没建立jpa对应的不许排除，直接转化
排除1，实体中注解排除@Entity
@JsonIgnoreProperties(value={"processLogs"})属性不进行json的转化，忽略这个属性的json转化
2，json时executive
中途有[]重复多个的为list
public String getWorkProcessLogById() {
String id=model.getId();
List<ProcessLog> a = new ArrayList<ProcessLog>();
a= this.getService().getWorkProcessLogById(id);
JsonConfig config = new JsonConfig();
config.setExcludes(new String[]{"troubleProcesOrder","workOrder","notice"});

String json = JSONArray.fromObject(a, config).toString();
  HttpServletResponse response =  ServletActionContext.getResponse();;
response.setCharacterEncoding("utf-8");
        ServletOutputStream out = null;
try
        {
        out = response.getOutputStream();
            out.write(json.getBytes());
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
        finally
        {
        try {
out.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
        }
        return null;
}
